E-body hardtop and vert door glass are not interchangeable.
The verts have a more sharp corner up near the windshield while the hardtops are very rounded in this region.
I cannot explain the radius differences you have at the corner near the rear quarter window.
Here you go.
Yellow vert is a 70 bumper on a 71. Black and white pic is a 71 bumper on a 71. Study the fit with the lower valence.
@Chryco Psycho reproduces the rubber bumpers. He took over from Gene Gregory years ago.
Very nice!
Welcome.
I think you have a ‘70 front rubber bumper.
The “ears” are supposed to align with the lower valence and not obscure the marker lights.
The '73 body manual has pretty much the same picture of the fender attachment as the '71 manual.
